Profile: Kelly, 23, bounced back from an early-season bout with elbow soreness that cost him about three months to make his way up to San Diego by late August. The former first-rounder (taken by the Red Sox in 2008) was impressive in his debut outing (six innings, three hits, no runs) but not good in his next five starts: 23 IP, 36 hits, 20 earned runs (albeit with a 22:8 strikeouts-to-walk ratio). The 6’3, 200 right-hander with big league bloodlines (son of Pat Kelly) has always been a favorite of scouts, but his stats have had trouble measuring up, especially at Double-A and above. Kelly’s athleticism could wind up being his saving grace -- formerly a two-way prospect at shortstop, he’s focused entirely on pitching only since 2010 -- as he sports a repeatable delivery and has displayed above-average control and command (2.4 walks per nine, career), making him the type of pitcher who could get better in the majors, if everything clicks into place. With the Padres rotation open-ended, Kelly will get plenty of chances to pitch in the bigs in 2013, and he could be a sneaky, cheap arm to own in NL-only leagues, especially if deployed at Petco.

The Quick Opinion: Even if the walls are coming in at PetCo, San Diego should still be a good place for a young pitcher to develop. Kelly still needs some seasoning, but there's a little more to him than the numbers might suggest.

Profile: Kelly, now 25, reached the Majors in 2012 but blew out his elbow and lost all of 2013 and most of '14 to the dreaded Tommy John surgery. The right-hander will likely open the 2015 season in either Double-A or Triple-A with an eye on returning to the majors at some point in the second half of the year. The lost development time will certainly do him no favors but he was a fairly polished product at the time of the injury. He has the ceiling of a number three starter but has a history of being more of pitch-to-contact guy with strong ground-ball rates rather than a big time strikeout machine. He has potential as a solid NL-only guy once he solidifies a role in the majors but might be a bit of a stretch as a mixed-league performer, at least in the early stages of his (restarted) MLB career. (Marc Hulet)

The Quick Opinion: A former top prospect, injuries have slowed Kelly's ascent and he enters 2015 with no defined big league role. He's a name to monitor somewhat closely as he could have some NL-only value in the second half of the year.

Profile: Long considered a unanimous top prospect, Kelly has struggled since he had Tommy John surgery in April 2013. The Padres seemed ready to give up on him as a starter -- converting him to a reliever for part of 2015 -- and now have dealt him to Atlanta as part of the Christian Bethancourt trade. It's not entirely clear what Kelly's role will be with the Braves. Whether it's in the rotation or the bullpen, my guess is that he'll start 2016 in Triple-A. (Scott Strandberg)

The Quick Opinion: Kelly is just 26 years old, so it's not unreasonable to think he could still put it all together at some point. However, I wouldn't place any bets on that happening in 2016. Feel free to ignore him in fantasy drafts.
